Abstract: Pixel circuits in an image sensor are sampled repetitively during an image frame period. At each sampling, a signal indicative of the photocharge integrated by a pixel circuit since last reset is compared to a threshold. If the integrated photocharge signal has not reached the threshold, the pixel circuit is permitted to continue integrating photocharge. If the integrated photocharge signal has reached the threshold, the pixel circuit is reset to remove integrated photocharge and photocharge integration for that pixel circuit is restarted. A corresponding pixel circuit value is recorded for the reset pixel circuit.

Abstract: Components of a memory system, such as a memory controller and a memory device, that reduce delay in exiting self-refresh mode by controlling the refresh timing of the memory device. The memory device includes a memory core. An interface circuit of the memory device receives an external refresh signal indicating an intermittent refresh event. A refresh circuit of the memory device generates an internal refresh signal indicating an internal refresh event of the memory device. A refresh control circuit of the memory device performs a refresh operation on a portion of the memory core responsive to the internal refresh event, at a time relative to the intermittent refresh event indicated by the external refresh signal.

Abstract: A system for controlling flight of an aircraft has sensors, a receiver, and a digital control system, all of which are carried aboard the aircraft. The sensors determine the position of the aircraft relative to the earth and the inertial movement of the aircraft. The receiver receives transmitted data communicating the position and movement of a reference vehicle relative to the earth. The control system calculates the position and velocity of the aircraft relative to the reference vehicle using the data from the sensors and the receiver and then commands flight control devices on the aircraft for maneuvering the aircraft in a manner that maintains a selected position and/or velocity relative to the reference vehicle. The system allows use of a graphical or tactile user interfaces.

Abstract: A flight control system for an aircraft is configured for receiving command signals representing commanded values of a location of a geospatial point and a radius about the geospatial point for defining a circular groundtrack. A sensor determines a geospatial location of the aircraft and provides a location signal representing the location of the aircraft.

Abstract: One embodiment of the present invention is a method for automatically controlling the conversion of a tiltrotor aircraft. An airspeed command for the tiltrotor aircraft is received. The airspeed command is converted to a pylon position. A difference between the airspeed command and a measured airspeed is calculated. The difference between the airspeed command and a measured airspeed is converted to a dynamic pylon position. A total pylon position is calculated from the pylon position and the dynamic pylon position. A pylon of the tiltrotor aircraft is moved to the total pylon position. Another embodiment of the present invention is a system for calculating a position of a pylon of a tiltrotor aircraft based on an airspeed command. The system includes an airspeed command module, a pylon trim position module, a dynamic pylon position module, and a pylon position module.

Abstract: The crimper has a pair of feed rollers to supply fiber traveling therebetween. The feed rollers rotate at a first speed. A pair of outlet rollers receive fiber from the feed rollers and rotate at a second speed slower than the first speed. A pair of side walls sandwich the feed rollers and the outlet rollers. A pair of floating scrapers are supported by move with the feed rollers, the outlet rollers and the side walls. Fluid is supplied to and ejected from the scrapers such that a fluid bearing is created at least between the scrapers and the feed rollers. There are two pairs of outlet rollers with a belt rotating about each pair of outlet rollers. For each pair, a first of the outlet rollers is adjacent to the scraper and a second of the outlet rollers is displaced from the scraper. A space between the scrapers defines a crimping chamber. The first outlet rollers are moved toward and away from one another, thereby causing the crimping chamber to open and close.

Abstract: A method and apparatus for locating the source of noise ingress into a CATV system return path by coupling a filter having a passband in the noise frequency bandwidth to the nodes between adjacent return path amplifiers. The filter is sequentially coupled to the nodes, working away from the CATV system headend. A signal level meter or the like monitors the effect on the noise of coupling the filter to the nodes. When a node is reached at which coupling of the filter to the node no longer has any effect on the signal level in the node, the source of the noise is isolated in the node immediately preceding the node under test.

Abstract: A system (10) for monitoring the ingress of noise into the return path (14) of a two-way CATV network comprises a detector circuit (16, 116) coupled to the return path (14) to receive a signal from the return path (14). The detector circuit (16, 116) provides an output signal indicative of the signal coupled from the network. A peak follower circuit (20, 120) coupled to the detector circuit (16, 116) stores a peak detected output signal from the detector circuit (16, 116). Illustratively, the peak follower circuit (20, 120) is coupled to the detector circuit (16, 116) through a filter circuit having a passband, for example, a low pass filter (18, 118). The peak follower circuit (20, 120) stores a peak detected output signal within the passband. A mixer (128) may be included for mixing the signal from the network with a local oscillator (126) frequency to produce a mixed signal, and for supplying the mixed signal to the detector circuit (16, 116).
